| In order to ensure the safety of rock-sheds、 nuclear power plants、 fuel tanks and/or other protective structures against impact loads、 many numerical and experimental researches have been carried out. However、 in order to rationally design this type of RC structures considering the performance up to the ultimate state、 impact resistant behavior and dynamic load carrying capacity for these should be investigated precisely. For these、 not only experimental study but also numerical one should be conducted.[*]From this point of view、 here、 in order to establish a rational numerical analysis method for real RC rock-sheds、 nonlinear finite element (FE) analysis was conducted based on the falling-weight impact test results for prototype rectangular RC girder with partially mounted sand-cushion. An explicit and three dimensional finite element code LY-DYNA is used for this study. |
